BACKGROUND/AIM: The aim of this study was to examine the extent to which additive genetic, shared environmental and non-shared environmental factors contribute to adolescent and preadolescent sleep problems.
The sample consisted of a cohort of 270 monozygotic and 246 dizygotic twins from a university-based twin registry.
Results demonstrated that genetic and environmental influences each appear to be important to adolescent sleep problems.
While the magnitude of genetic influence on sleep problems was consistent with findings from the adult literature, it was smaller than in studies with younger children, suggesting genetic effects may be less influential in adolescence and adulthood.
背景/目的:本研究旨在探讨加性遗传、共享环境和非共享环境因素对青少年及青春期前睡眠问题的影响程度。
样本包括来自大学双胞胎登记处的270对同卵双胞胎和246对异卵双胞胎。
结果表明,遗传和环境影响对青少年睡眠问题似乎都很重要。
虽然遗传对睡眠问题的影响程度与成人文献中的研究结果一致,但小于对年幼儿童的研究,这表明遗传效应在青少年期和成年期的影响可能较小。
